JAceUARD-MACHINE FOR Loolvls.

SPECIFICATION forming part of Letters Patent N o. 651,120, dated June5,1900. Application led September 17, 1898. Serial No. 6934146. (Ilomodel.)

following is a specification, reference being had therein to theaccompanying drawings.

My invention relates to jacquard-machines of that class in which twopattern cylinders or prisms are employed 'for cooperation with,

the needles, each of such pattern cylinders or prisms having it-s ownpattern and the two pattern cylinders'or prisms being brought intoaction in connection with the needles alternately. It is customary toemploy this arrangement for weaving goods having end borders orcross-stripes'at intervals, one of the pattern cylinders or prismscarrying the pattern for the border or cross-stripe and the othercarrying the pattern for the body or intervening portion of the goods.

The invention includes various improved and novel combinations-of parts,including devices whereby to bring automatically ther respective patterncylinders or prisms into action alternately at the required times in theworking of the jacquard-machine.

The invention will be described first with reference to the accompanyingdrawings, in which latter .l have represented one embodiment thereof,after whichl the invention will be particularly pointed out in theclaims at the close of this specification.

Figure 1 of the accompanying drawings shows in side elevation certainportions of a jacquard-machine of the class aforesaid with the saidembodiment of my invention applied thereto, only such parts beingrepresented as are required in order to clearly indicate the nature andrelations of the invention. Fig. 2 is a view in vertical transversesection of a jacquard-machine of the said class, showing certain of theworking parts thereof. Fig. 3 is a View showing certain parts in plan.Figs. 4 and 5 show details.

In the drawings, 7l 71 designate certain of the hooks or hooked uprightsof a jacquardmachine, the rest of the series being omittedI for the sakeof securing simplicity and clearknown character.

ness. l and 2 designate certain needles of the series of needlesengaging with said uprights 71 7l, the greater part of the said seriesof needles being omitted for the reason just stated. The needles 1 2 arearranged and supported in usual manner and engage with the stems of theuprights in customary fashion, the opposite ends of the said needlesbeing supported in stands l2 and 15, of well- 16 designates a patterncylinder or prism arranged to cooperate with the said needles 1 and 2.Around the said pattern cylinder or-prism 16 a series of perforatedpattern-cards (not shown) is intend ed to pass in practice, the saidpattern-cards being presented successively against the ends of theneedles 14 and 2 by the operation of the pattern cylinder or prism, aswill be understood.

The invention which is about to be described may be utilized inconnection with either a single-action jacquard-machine or a doubleaction jacquard machine. I have illustrated it as embodied in adouble-action jacquard-machine-that is to say, in a jacquard-machinehaving two sets of moving grid-blades 72 72 and 82 82, respectively, thesaid griff-blades being mounted in the griffframes 7 and'8,respectively, and the said griff-frames being applied to guide-rods 18and 19, which latter are arranged to slide as usual in guides orbearings provided therefor on the frames of the jacquard-machine, thesaid guides or bearings, however, being omitted from the drawings forthe sake of clearness. Movement is communicated to the griffs throughrods 9 and 10 from suitable moving parts of the mechanism, (not shown,)

and thereby in usual manner the two grids are raised alternately.

1l designates the usual bottom plate. v A second pattern cylinder orprism is'shown at 17, and around the saine is intended to pass inpracticea second set of pattern-cards. (Not shown.) For convenience thepattern cylinder or prism 17 may be designated the auX- iliary patterncylinderor prism and that designated l the main pattern cylinder orprism. Both of the pattern cylinders or prisms serve to actuate theneedles 1 2, and thereby control the engagement of the up- IOO rightswith the moving griiis, although they are not both operative in thisrespect at the same time. The auxiliary pattern cylinder' orprism 17preferably, as in the drawings, cooperates with the needles 1 2 throughthe medium of a second set of needles, certain of which are shown at 56, and which needles may for convenience be designated herein theauxiliary needles,the opposite ends thereof being supported in stands 13and 14. Springs 121 121 are shown applied to the various needles 1, 2,5, and 6 in usual manner and operate to press the said needles towardthe respective pattern cylinders Aor prisms. The auxiliary needles 5 and6 are connected operatively in suitable manner with the needles 1 and 2for the purpose of enabling the said needles 1 and 2 to be operated whendesired by or through the said needles 5 and 6. 1n some cases the modeof connection may be varied from that herein illustrated. In the presentcase the needles 1 and 2 are shown connected with the needles 5 and 6 bymeans of levers in the form of wires 3 and 4, which last, respectively,at or near their opposite extremities pass through eyes in the needles1, 2, 5, and 6, each lever or wire 3 at its upper extremity passingthrough an eye of a needle of the auxiliary set 5 6 and at its lowerextremity passing through an eye of a needle ol' the main set 1 2. Atintermediate points in their length the levers or wires 3 f1 takebearing against transversely-extending rods 20, the latter constitutingfulcra for the said levers or wires when they are moved in consequenceof endwise movement of the auxiliary needles 5 and 6. The rods 20 arearranged in an inclined series in supports 2l, as shown clearly in Fig.2, in order that each lever or wire 3 f1 may have its fulcrum-rod 20located substantially equidistant between the auxiliary needle and mainneedle with which it coacts. Enlargements or heads 73 73 on the wires orneedles and et support the latter vertically by resting on the uppersides of the eyes of the auxiliary needles 5 and 6. It will be obviousthat when one ot' the auxiliary needles 5 6 is moved endwise through thepressure of a blank or unperforated portion of a pattern-card on theauxiliary pattern cylinder or prism 17 the corresponding needle oi themain series 1 2 will be moved endwise through the action of theintermediate wire or lever of the series 3 ein precisely the same manneras if such needle of the main series were pressed back by a blank orunperforated part of a pattern-card on the main pattern cylinder orprism 1 6. Thus the main needles 1 2 and the hooks or uprights 71 71 inengagement therewith may be borne to the left in the drawings throughthe action of pattern-cards `on either pattern cylinder or prism. 8ofar, therefore, as the matter of determining the engagement of theuprights 71 71 With the moving griff-blades is concerned it isimmaterial which of the pattcrncylinders or prisms is brought intoaction.

The pattern cylinders or prisms 1G and 17 are mounted, respectively, incarriers or battens 26 27. (See Fig. 1.) The said carriers or battensmay be of any approved construction and arrangement. The inode ofmounting the same may be varied. Herein the carrier or batten 26 isprovided with rods 28, that are iitted to guides 281 281 on theframework 25 of the jacquard-machine, the said rods 28 being arranged toslide horizontally through the said guides. In like manner the carrieror hatten 27 is provided with slide-rods 29, that are fitted to guides291 on the framing With the carriers or battens 26 27 I com binesuitable mechanism for operating the same, such mechanism includingclutch devices or clutches by means of which the rcspective carriers orbattens may be connected with the said mechanism and disconnectedtherefrom. The preferred mechanism consists ot` reciprocating arms orbars 32 33, hereinafter terme( actuators,since theirfunction is tobecome connected with the carriers or battens and to operate the same.Any suitable arrangement for reciprocating the said actuatorssimultaneously with each other, but in opposite directions,may beadopted in practice; but I havesho'wn the inner ends of the sameconnected pivotally with a rocker-arm or rocker 30 at opposite sides ofthe pivoted stud 48, by means of which the said rocker is mounted on theframing 25 of the jacquardmachine. The said rocker 30 is intended to beoperated in practice by any of the means usually employed for actuatingthe like parts in jacquard-machines. The outer ends of the saidactuators are supported by means of pins 361 371, projecting fromcollars 36 37, respectively, made fast on the slide-rods 28 29, the saidouterends being `l'ormed with longitudinally-extending slots 321 331,which receive the said pins. During the outward movement of an actuatorthe shoulder at the inner end of its slot 321 or 331 in case itencounters the pin 361 or 371 acts against the said pin to force thecorresponding carrier outward into the position that is occupied by thelefthand carrier in Fig. 1, the carrier remaining in this, its idleposition, so long as it remains unclutched from its actuator. During thetime while one of the carriers remains in the said idle position theother carrier remains clutched to its actuator and moves therewith. Theclutch that is employed in connection with each carrier consists, in thepresent embodiment of the invention, of a simple hook or latch 34 or 35,which is pivoted to'the actuator, as at 34.1 or 351, adjacent to theslot in the latter. The engagement of the said hook or latch with thepin 361 or 371 is intended to occur when the actuator has reached theoutward extreme of its movement, the inner end of the corresponding slot321 or 331 being then closely adjacent to the said pin, and thereby thesaid pin is held closely between the said hook or latch and the saidinner end of the slot, which causes thc carrier IOO IIO

or hatten tobe moved out and in in unison with the actuator. For thepurpose of effecting the engagement and disengagement of the hooks orlatches 34 35 with the pins 361 371 and controlling the same so asY tooccasion the operation of the two carriers or battens alternately Iemploy in the present instance a controlling-lever 31, which is shownpivoted upon the stud 48, one arm of the said lever extending under apin 342, projecting from the hook or latch 34, and the other arm thereofextending under a pin 352, projecting from the hook or latch 35. In oneposition of the said controlling-lever it holds hook or latch 35 raisedout of engagement with pin 371 and permits hook orlatch 34 to remain inengage# ment with pin 361. (See Fig. 1.) The pins 342 352 slide alongthe plain upper surfaces of the arms of the controlling-lever. In theother position of the controlling-leverit holds the hook or latch 34raised out of engagement with pin 361 and allows hook or latch 35 tobecome and remain engaged With pin 371.

In accordance with the present invention I provide automaticclutch-operating devices whereby to connect the two carriers for thepattern cylinders or prisms alternately at the required intervals withthe actuating mechanism therefor. Thus in the present embodiment of theinvention the controlling-lever 31 is connected by means of a wire 311,with an arm or lever 39, which is pivoted upon the stud or pin 49,mounted on the framing 25 of the jacquard-machine. With the arm or lever39 is connected one end of a cord or the like, as 391, which extendsaround sheaves or pulleys, as 1392 1392, and has the other end thereofconnected to one of the nprights 71. When the said upright is caused tobecome engaged with the rising griff and is raised thereby, movement istransmitted through the cord 391 to the arm or lever 39, moving it inone direction, the controlling-lever 31 being correspondingly actuatedfrom arm or lever 39 through the Wire 311. Thereby the saidcontrolling-lever is shifted in position, so as to permit one of theclutches-say 35--to engage with the pin, as 371, of the correspondingcarrier or hatten, as 27, whereby the latter is brought into action, theother clutch being disengaged from the pin of the other carrier orhatten and the latter being permitted to become idle for the time being.For the purpose of causing the controlling-lever 31 to gravitate to itsformer position when such return is permitted to take place either thelower arm of such lever is made Weightierthan the other arm thereof inobvious manner or a spring, as 481, Fig. 4, is combined with thecontrolling-lever, the said sprin g being shown herein mounted upon thestud or pin 48, with one end thereof connected to lever 31 and the otherend thereof connected to collar 47, fast on stud 48.

40 designates a locking Varm or lever by means of which the arm or lever39 is held in either of its extreme positions until a shift thereof isrequired to be made. The said locking-lever 40 is pivoted upon pinorstud 50, projecting from framing 25, and has a toe 401 engaging withtwo teeth 392 392 upon the arm or lever The said toe 401 of the lockingarm or lever 40 engages alternately with the respective teeth 392 392 ofarm orlever 39 to hold the latter in its said extreme positions,respectively.

To carry the lockingarm orlever 40 toward arm or lever 39, a spring 402,Fig. 5, is combined with the former, the said spring being mounted onstud or pin 50 and having one end thereof connected with the locking armor lever and the other connected with the framing 25. For the purposelof operating the locking arm or lever 40 automatically Whenever it isdesired to disengage the same from the arm or lever 39 and permit theposition of the latter and of the controlling-lever 31 to be altered thesaid locking arm or lever 40 has ,connected therewith a cord 403,extending around sheaves or pulleys 404 404 and also connected with oneof the uprights 71, as shown.

The usual actnating-pawls for the main pattern cylinder or prism 16 areshown at 43 44, the same being connected by rod 45, as usual, While theactuating-pawls for the auxiliary pattern cylinder or prism 17 are shownat 41 42, their connecting-rod being designated 4G.
